BUG/STYLE: This should be explicit.

Acknowledged. This constructor now accepts 2 arguments.

Do blocks not allow you to forward declare such structures?

[Eugene But (OOO till 7-30), 2015/08/07 02:27:20]

No you can't forward declare this block without including cert_verify_result.h,
because block takes CertVerifyResult by value.

Weak has a particular meaning in Chromium (c.f. WeakPtr); this does not appear
to be a common term in Chromium code, although I'm guessing you're using the iOS
terminology.

[Eugene But (OOO till 7-30), 2015/08/07 02:27:20]

Good catch. Changed to "unowned", because this is not a weak pointer even by iOS
terminology.

This comment doesn't seem to help documentation much :/

Why are you creating your own NetLog? Why is the adapter-caller not supplying it
as part of the Params / Verify call?
